SPECIFICATION forming part of Letters Patent No. 252,300, dated January10, 1882.

Application filed November 19, 1881.

To-all whom it may concern: I

Be it known that 1, JAMES W. WOMELS- DORFF, of Guyandotte, in the countyof Qabell and State of \VestVirginia, have invented certain new anduseful Improvements in Batchet-Wrenches; and I do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing bad to the accomence marked thereon, which form part of this Myinvention'has reference to nut-wrenches which can be adjusted forturning a nut-either to the'right or to the lelt.

The nature of my invention consists in certain novel means whereby asocketed hub having right and left ratchet-teeth can be locked by meansof pawls acted .on by springs and inclosedin the stock of the leverhandle, in combination with a key and such a constructo'be retracted andfreed from its ratchet. The invention also consists in a novelconstruction'of the stock of the lever-handle to admit the use of thesaid hub and pawls, as will be hereinafter explained.

In the drawings, Figure 1 is a plan view;- Fig. 2, vertical longitudinalsection on line y 3 Fig. 3; Fig. 3, vertical section on line as a, Fig.2. I V V The following is a description of my invention: A designates alever-handle of any desired length, and B is the channeled stock of thishandle; 0 is an extension beyond the stock, and D is a circular bearingformed on the ex- On one face of the channeled stock B are formedunder-beveled flanges b b. All of these parts I am able to constructentire.

E designates the wrench-hub, which is applied so that it can turn on thecircular hearing D, and is held in place thereon by a retaining-plate,F, which is confined to the stock 13 by means of the flanges b b and ascrewyc.

cover the channel in the stock.- The wrenchhub is constructed with rightand left ratchetteeth at d on opposite sides of a division, 0.

by springs g g at their rear ends.

'atit'.

(No model.)

The hub has a hole centrally through it, and also a prismatic recess, f,in one end to receive'a not which is to be screwed on or unscrewed froma bolt.

If desired, the recessed end of the hub may be made separate from thehub, and rigidly but removably secured to it-in any suitable manner.This will allow the use of interchangeable portions having nut-recessesof different sizes.

Gr G designate two pawls or bolts, having beveled noses adapted toengage with the right and left ratchet-teeth d d of the wrenchhub,against which teeth the pawls are held The pawls are applied in thechannel of the stock B, and inclosed therein by means of theretainingplate F, above referred to.

It will be seen by reference to Fig. 2 that the pawls are notched, so asto leave shoulders.

These notches allow the use of a key, J, for retracting either one ofthe pawls and freeing the same from its ratchet-teeth. The key-holes aremade through the cheeks of the stock B, and the key acts against theshoulders t of the pawls.

What [claim as my invention is- -1. The combination of the perforatedcircular bearing D. on one side of the enlarged end of the handle A, theperforated right-and-left ratchet-hub E, fitted on said bearing, the di-8c vision 0 thereof, the nut-socket in one end of the hub, the removableretaining-plate F, and the spring-actuated pawls inclosed in the handle,substantially as described.

2. The combination of the right-and-left ratchet-hub E, the bearing D,and retaining plate for the hub,the' spring-actuated pawls G .G, for theright and left teeth of the said hub, the shoulders t i on these pawls,the lc'ey, and the channeled stock, substantially as: described. V

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
